Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Tripe
- Forms the body of the dish, becoming tender through long gentle simmering.
- New milk
- Cooks the tripe slowly and forms the base of the sauce.
- Onions
- Add sweetness and savory flavor to the sauce as they cook.
- Baked flour
- Thickens the milk into a smooth, lightly bodied sauce.
- Thick cream or fresh butter
- Adds richness and a silky finish to the sauce.
The step that matters
Stirring in the cream or butter. Adding rich fat at the end while the sauce is very hot and stirring quickly helps it emulsify smoothly into the thickened milk instead of separating or becoming greasy.
Swap the white pepper
How well each one fits the dish's main ingredients (milk, onion, sugar, mustard, flour, nutmeg, cream):
- Cinnamonfits better
- Cardamomfits better
- Capersfits better
- White pepperthe original
Fit is the average pairing score against milk, onion, sugar, mustard, flour, nutmeg, cream. Candidates are from the same food group and used in at least 100 recipes.
